★★★★★LoganBest camp EVER i am counted as little shaff here. Also kian should have never got fired. He only tried to help me and was best counselor ever. Jake is second best besides hermes. Everyone says “oh camp foundations is better with there $3 doller oreos and $20 shirts.” Camp hollis has free shirts and da kohana stick (a hidden stick which is whoever’s the last to find it gets icecream).
★★★★★Liam ShaffnerMe and my brother’s go to this camp. All of the counselors here have a sense of humor and are energetic. They offer daycamp and overnight for the campers. Anthony is the best counselor there though. He has so much energy and is funny, he always makes me laugh and he is good at sports. All of the other counselors are good too. I am so excited for when I’m going to camp soon, this is the perfect place for kids to enjoy their summer!
★★★★★John EastmanFamily rented the facility for a birthday party. Bring your own food or use the professional kitchen to prepare your food. The place is very clean and must be cleaned before you leave. The community room off kitchen is setup likes school cafeteria.
★★★★★TheRealSigmaCamp Hollis was absolutely incredible this year! From the moment I arrived, I knew I was in for an unforgettable experience. Huge thanks to my amazing counselors—Dan, Rashad, and Hunter—for everything they did to make this week so special. They were not only supportive but also really went above and beyond to make sure every day was packed with fun, learning, and personal growth. Dan brought so much positive energy and enthusiasm to everything we did, always making sure we felt comfortable and encouraged. Rashad’s leadership skills were on another level—he was a true role model for all of us. And Hunter, with his incredible sense of humor and creativity, really made every activity feel like a new adventure. I’m so grateful for the bond I built with each of them, and I couldn’t have asked for a better team of counselors. I felt truly supported, challenged, and inspired every step of the way. This experience will stay with me for a long time, and I’m already looking forward to next year! Thank you all for everything! You made this year one of the best ones yet. 👏🏼👍🏻
